How to combat climate change is a highly politicized issue worldwide. For many, the arguments surrounding global warming and the ways to combat it can be convoluted and confusing.
Delivering the first of the Sydney Ideas lectures for 2010, world-renowned climate scientist Michael Oppenheimer outlines the evidence for global warming and explains how it was gathered.
Michael Oppenheimer is a Professor of Geosciences and International Affairs at Princeton University. He was the Lead Author on the third and fourth assessment reports of the Intergovernmental Panel on Climate Change, published in 2001 and 2007 respectively.
Before joining the faculty at Princeton, he spent 20 years as chief scientist at The Environmental Defense Fund.
Is the Earth really heating up? Climate scientist Michael Oppenheimer forecasts 2010 as a probable "cooling decade," but anticipates an increase of up to 7 degrees Celsius by the end of the century. "Not every decade is going to be necessarily warmer than the decade before," he says. "It's a long term phenomenon."
